This repository houses core CTL library functions used by the ACES system. These functions provide the foundational building blocks upon which higher-level ACES transforms are constructed, including:
-
Rendering algorithms used in ACES Output Transforms (e.g., tonescale, chroma compress, gamut compress)
-
Utility functions for common operations (e.g., clamping, matrix math)
-
Fundamental color science operations (e.g., transfer functions, matrix conversions, chromatic adaptation)
